SDK Tools needs simplified building and dependency resolution

We have several very large projects that require building combinations of Java resources as well as front end components into a single deployable file (a Java "war" file). The build process runs under Maven and currently uses JSBuilder2 as one of the steps to build a minified single javascript file with many hundreds of custom js classes. Everything works perfectly - the application is simple to maintain, build and deploy.

The new SDK Tools lack simplified options for building. We are experienced users and *know* which ExtJS 4 / Touch2 components our application uses. We do not create projects using the SDK nor do we want to. We can, however, create an ext.jsb2 equivalent file containing all "requires" entries across all our js files (and could even automate this in our Maven build). We would then like to run something like:

sencha build my-required-extjs-files.jsb2

which will scan the specified jsb2 file, resolve any dependencies, and create a minified ext-min.js file specific to the needs of the project. This would then become part of our build process.
